Anny (anacgarcia on here) also makes invitations, pretty sure she does boarding passes. Also, you can google Aylee designs, she makes them as well.
But really, you might want to reconsider making them. Just check out a few threads of people that have made them and you can see that it was actually pretty fun to design them. And then putting them together was tedious, but not hard at all. I also had mine printed, cut, stapled and perforated at a printing company, which saving me mucho time.
